Adding multiple processing cores on the same chip has become the de facto design choice as we continue extracting more and more performance/watt from our chips in every technology generation. In this context, the interconnect ...

The U.S. Department of Energy has identified "sensing and measurement" as one of the "five fundamental technologies" essential for driving the creation of a "Smart Grid". Consumers will need "simple, accessible..., rich, ...

Integrated photonics has emerged as an I/O technology set to disrupt the communication fabric of many-core computer systems. The optical technology uses wavelength-division-multiplexing and a high degree of integration in ...

Digital techniques have had longstanding use in both the operational control and signal processing efforts associated with phased array antennas. Fundamentally, these techniques have served to provide additional levels of ...

As the number of materials that are thermally-drawable into fibers is rapidly expending, numerous new multimaterial fiber architectures can be envisioned and fabricated. High-melting temperature metals, compound materials, ...

Technology scaling poses challenges in designing analog circuits because of the decrease in intrinsic gain and reduced swing. An alternative to using high-gain amplifiers in the implementation of switched-capacitor circuits ...

One difficulty of programming multicore processors is achieving performance that scales with the number of cores in the system. A common performance optimization is to increase inter-core parallelism. If the application ...

The continued improvement of transistor performance has increased the limit on the peak energy-efficiency of wireless transmitters. Nevertheless, the average efficiency with mobile multimedia communication is decreasing ...

The desire for ubiquitous connectivity is pushing radios towards highly-integrated, multi-standard and multi-band implementations. This thesis explores architectures for next-generation RF frontends, which form the interface ...

Due to the unique combination of large critical breakdown field and high electron velocity, GaN-based high electron mobility transistors (HEMTs) have great potential for next generation high power RF amplifiers. The ...

Analog-to-digital converters (ADCs) are essential building blocks in many electronic systems which require digital signal processing and storage of analog signals. Traditionally, ADCs are considered a power hungry circuit. ...

We often build complex probabilistic models by composing simpler models-using one model to generate parameters or latent variables for another model. This allows us to express complex distributions over the observed data ...

The process of optimizing programs and libraries, both for performance and quality of service, can be viewed as a search problem over the space of implementation choices. This search is traditionally manually conducted by ...

Outside the factory, robots will often encounter mechanical systems with which they need to interact. The robot may need to open and unload a kitchen dishwasher or move around heavy construction equipment. Many of the ...

Thermo-electric heat exchange in semiconductor light emitting diodes (LEDs) allows these devices to emit optical power in excess of the electrical power used to drive them, with the remaining power drawn from ambient heat. ...

Our world is constantly changing, and it is important for us to understand how our environment changes and evolves over time. A common method for capturing and communicating such changes is imagery - whether captured by ...
